"Bad actor" pumps are those pumps that have trouble with frequent and repetitive failures. In many cases, the source of the problem is an ANSI pump trying valiantly to handle a liquid well beyond the range of its design rating.of 300 degs. F.
Outsourcing of non-core operations within a company, large or small, is now a well established corporate strategy. By entrusting services such as IT support, accounting, human resources and other back office activities to specialist firms prepared to do the job at an acceptable price, chemical companies can concentrate on their main business where they are the specialists. That's the theory, at least.
A recent poll provides an industrial perspective and points up its troubling implications. As many universities are discovering, science and technology arent as popular as they once were. It's your job to spread the word, however small.

Chemical Processing's Plant Innovation Award recognizes ordinary engineers for solving difficult technical problems with creativity and dogged determination. Praxair's Geismar plant gains this year's honor for optimizing the performance of reforming units.
Chemical processors face significant challenges in controlling fugitive emissions. The emissions escape from valves, compressors, pumps, piping components, etc. It is a difficult task, but necessary to avoid penalties and other liability.
Theres no simple solution to achieving accurate temperature measurement. Its a combination of knowing the inherent accuracy of particular sensor types, and how environmental factors can create further measurement uncertainty and the sensor calibration techniques available to reduce this uncertainty.

The one-day conference will include presentations, a demonstration from key industry leaders, several workshops, and award activities to recognize contributions from PIP Member Companies participants.
Pipe strain can cause premature failure of pumps. This can frequently be absorbed by a flexible pipe coupling... but only if that pipe coupling is properly installed. Merely putting it into the line without any support, will not achieve any significant relief from the pipe strain. In order to protect the pump against the pipe strain, it must be anchored.
